I’ve tried it. Don’t like it. With all the messing around you have to do to get it to brew properly using Keurig equipment, it seems like reinventing the wheel. In my opinion, the Keurig is nothing but a dumbed-down, overpriced way to make a hot beverage.

I have been experimenting with Keurig for a couple of months now. I find that the Twinning’s K cups work just fine…if a bit strong on the first brew. And the non-flavored work better i.e. English Breakfast is fine, Earl Grey is disappointing. For loose steeping, I have two suggestions.
The first is the eKobrew K cup replacement. It distributes the water better and does a better job of getting the water through the leaves. I find that it works better with twice as much tea as I would use for a steeping (about 6gm or two Teelamaß scoops). This observation applies to whole leaf tea; ground or fines tea would be closer to normal.
The second thing I’ve found that works a bit better than Keurig’s grey filter adaptor basket is to reuse an old K-cup (use old coffee ones for coffee and old tea for tea). Remove the foil top, empty the contents, leaving the paper filter in place. Wash it out and let it dry over night. To use it, put your loose tea/coffee into the cup and put the cup into Keurig’s grey filter basket holder. You’ll have to apply a lot of pressure to get the filter basket lid on the first time. Insert into the Keurig and brew. The paper seems to slow the water a bit, making for a better brew than the stainless steel basket.
For loose tea in the Keurig, With either approach, I like to brew two smaller cups versus one larger, as I think the wet time between brewings helps bring out more flavor from the leaves.

I agree that it’s probably not ideal to use loose leaf tea in a reusable kcup because you won’t be getting the most out of your tea leaves. If you’re adamant on using the keurig, you should probably try the tea companies that make kcups. They are probably ground up to fine powder so it’s easier to get the flavor out of those compared to full loose leaves.

I make my teas in my Keurig Machine and it comes out pretty good . I just got my keurig and I love tea so I thought what if I get a reusable k cup and cut open a tea bag and pour the loose tea in the reusable k cup and brewed it and it actually came out pretty good please tell me what you think if you try this ?

At work we actually have tea k-cups. It’s not the greatest tea but it works in a pinch. However they are switching back to drip coffee/tea because the cost apparently was greater than they anticipated as well as the environmental impact.

I tried to brew dragon well in a Keurig today at my mom’s house. She is new to tea and used Keurig for coffee, so she wants to use it for tea. Anyway, the tea brewed fine surprisingly, but it did have an overwhelming coffee flavor. I would recommend that if this is the way you insist to brew try to use a machine that is dedicated just to tea. Here’s a photo: http://instagram.com/p/TMxVDlr-RT/
